so i have been experimenting on what is causing the click. so i removed the axles and filled the tube with grease. the click was gone with no new parts. it lasted sill it pushed most of the grease around the splines. it took a few weeks till it started clicking. so the click must be the spline end of the axle in the diff. as it rolls with resistance it is jarring around. no how to pertinently fix this somehow.
